Check Digit Verification of cas no

The CAS Registry Mumber 33968-14-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,6 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33968-14:
(7*3)+(6*3)+(5*9)+(4*6)+(3*8)+(2*1)+(1*4)=138
138 % 10 = 8
So 33968-14-8 is a valid CAS Registry Number.

Selective formylation of alcohols in the presence of phenols with chloral

Ram, Ram N,Meher, Nabin Kumar

, p. 2997 - 3001 (2002)

Primary and secondary alcohols were formylated selectively in the presence of phenols by stirring with chloral in acetone over anhydrous K2CO3 at ambient temperatures in high yields.

Metal-free DDQ-mediated oxidative C-O coupling of acetalic sp3 C-H bonds with carboxylic acids

Li, Jiang-Sheng,Xue, Yuan,Fu, Dong-Mei,Li, Dao-Lin,Li, Zhi-Wei,Liu, Wei-Dong,Pang, Huai-Lin,Zhang, Yue-Fei,Cao, Zhong,Zhang, Ling

, p. 54039 - 54042 (2015/02/05)

A simple and efficient DDQ-mediated oxidative C-O coupling reaction between acetalic sp3 C-H and carboxylic acid O-H bonds has been developed. This novel transformation smoothly proceeds without any metal catalyst and allows for the highly efficient synthesis of (un)symmetric glycol diesters in a single step. This journal is
